IMPROVEMENT IN MACHINE FOR REMOVING BURS PROM WOOL'.

TO ALL PERSONS TO WHO-M THESE PRESENTS SHALL COME:

Be it known that I, ZIBA PARKHvURS'r, of Milford, in'the county ofWorcester, and State of Massachusetts, have made a new and usefulinvention having reference to Machines for Removing Burs from Wool; andI do hereby declare the same to be fully described in the followingspecification, and represented in' the accompanying,r drawings, ofwhich-n Figurc l is a. vertical and longitudinal section of it.

FigureQ is a -top view of a burring .machine provided with my invention.

Figure 3' is an under side view of the bur box of such machine with myimprovement or improvements conneeted therewith.

In such drawings, A denotes the'framc of the machine; B isthe main cardor toothed cylinder; C C, the feed-rollers; and D the rotary beater orbur discharger, such beingl the parts common to an ordinary burringmachine. D is what I term the bur bex, which is placed over, thefeed-rollers and near to the cylinder B, and is connected by'hinges, aa, to two adjustable slide-bars, .E E, which rest on the top of thecheek-pieces or guides F F, and are connected thereto by set-screws, Z1b, which go down through slots, c c, in the said bars, and screw tol theguides F F. The hinges enable the bur box to be turned from a horizontalposition back into a vertical or'somewhat inclined one, for the purposeof facilitating the removal of the burs o1' fibrous or other matterswhich may collect on it. This bur box is open in front and closed inrear.` To its bottom I apply an adjustable plate Gr, fixed to the box bymeans of screws or devices, shown -at d d, by which it may be adjustedso as to bring its front edge close to or nearly against the teeth ofthe main cylinder, .This plate I term the induction plate, its objectbeing to press the wool into the spaces between the teeth of thecylinder of the bres of the wool or material to be treated'. I alsoapply to. such bur box one or more combs or toothed plates, II I, whichI arrange over the induction plate in the manner as represented in thedrawing. Theteeth of these combs may be of such incness as .muy benecessary, the object of the combs being to disturb or loosen up thewool which may lie o n the surface of the cylinder, so as to cause such,and particularly loose filaments of such, to be caught by the teeth ofthe cylinder. vThe combs and the induction plate have'been found to beexcellent additions to theburring machine, as they operate to preventmuch waste of theiibres, and cause the main cylinder to perform its dutyto much better advantage than it will without snch appliances, or eitherof them. Each comb may have adjusting devices by which it may be set inproper relation with the cylinder, or the comb may be-without such, butI prefer that the ,upper of the two should at least have suchadjustments. By applying the induction plate and combs to the bur boxthey may be turned up with it, so as to'enable an attendant to gainready access to the feed-rollers when necessary. v I

In the operation of my invention the fibres ofthe material containingthe burs after being drawn from the feed-rollers will, by the inductionplate, be crowded closely up to andbetweenthe teeth ofthe cylinder B,and, should any of the fibrous material after this project beyond theteeth, such material will be acted on bythe combs, and by them will beturned up and from thel bui-sv pressed inbetweenthe teeth in order thatthe beater may more readily detach the burs with as little of the{ibrous material adhering to them as possible. The purpose of the burbox'being well understood needs not be herein described. l

I make no claim to a burring, cylinder, however it may be constructed;nor do I claim any other part of the machine except -it be the bur-boxaudits appliances,

What I do claim as my invention is as follows: v

I claim the application of the induction plate G, or its equivalent,to', or its combination with, the barring machine, so as to operato withthe main cylinder thereof, substantially as and for the purposespecified.

I I also claim the combination and arrangement of one or more combs withthe burring machine, so as to operate with thc'main cylinder thereof,substantially as and for the purpose hereinbefore explained.

i I also claim the application of the induction plate and the combs, oreither of them,to the bur box, so as to be movable therewith. asdescribed.
